ARM and Microsoft Working Together on 64-bit Windows for ARM Processors

No sooner than ARM showed off its 64-bit Cortex-A50 series of processors came the news it is working with Microsoft to develop a 64-bit Windows for ARM processors. Microsoft Surface tablets running Windows RT are all 32-bit, unlike Windows 8, which also has a 64-bit version. The 32-bit limitation of Windows RT means memory capabilities pale in comparison to Windows 8, but a 64-bit Windows RT would level the playing field. ARM didn't reveal any specific release date for the 64-bit Windows RT, but the Cortex-A50 series is expected to arrive in servers and mobile devices in 2014. It's possible we'll see a 64-bit Windows RT around that time, and it'd be a good thing, too, considering 64-bit apps would need to be developed. There are other challenges as well, but at least there should be plenty of time to iron everything out.
